Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed September 18, 1917. Serial No. 191,914.

full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to stamp racks.

The object of my invention is to provide a rack capable of supporting a plurality of stamps and combined with a mechanism for moving said stamps and stopping them at pre-determined locations so that any one of said plurality of stamps can be readily selected for use.

In the drawings Figure 1 represents a front view of a stamp rack equipped with my improved operating mechanism.

Fig. 2 is a view of some of the parts shown in Fig. 1 looking in the direction of the arrow 2.

Fig. 3 is an enlarged view of the parts shown in Fig. 2 looking in the direction of the arrow 3.

Fig. 4 is a view of some of the parts shown in Fig. 3 looking in the direction of the arrow 4.

Fig. 5 is a view of some of the parts shown in Fig. 2 looking in the direction of the an row 5.

15 represents a casing which is formed of a bottom 16, a right side 17 and a side corresponding thereto, (not shown) at the left of the stamp rack, a front 18, a top 19 and a suitable back, not shown; these parts may be formed of wood, metal or any suitable composition, and joined together in any approved way.

Near the center of the side 17, a bearing boss 20 projects through a hole provided in said side. the inner face of said boss being flush with the inside of the side 17. A shaft 21 is revolubly mounted in a hole provided within the boss 20 and the inner end of said shaft fits tightly within a metallic flange 22 and is secured thereto by means of the pin 23. The metallic flange 22 is secured in any approved manner to the flange 24, which is preferably formed of wood.

On the left side of the stamp rack, a side similar to 17 is employed and this supports a boss similar to the boss 20. A shaft similar to21 is supported in the boss on the left side of the stamp rack and to'this boss is secured a flange similar to the metallic flange 22. A wood flange similar to the flange 24 is secured to said metallic flange at the left of the stamp rack and a plurality of shelves such as 25 is secured between the flange 24 and the wood flange at the left of the stamp rack. Hence, it is evident that the flange 24, its similar at the left of the stamp rack and the shelves 25 form a unitary structure which is revolubly supported by the shaft 21 and its similar at the left of the stamp rack, said shafts revolving freely in the boss 20 and its similar at the left of ing supported and guided in any approved manner but preferably as shown in my application for U. S. Letters Patent for stamp racks Serial No. 191913-Case D-filed on even date herewith. The means for supporting the stamps being described and claimed in'said application will not be here inafter referred to.

To the outer end of the shaft 21 a bevel gear 27 is secured by means of the pin 28 and a second bevel gear 29 fits tightly upon the shaft 30 and is secured thereto by means of the pin 31. The shaft 30 revolves freely within the bearing 32. said bearing and the boss 20 being formed integrally with the bracket 33 and with the flange 34, the latter being secured to the side 17 by means of screws such as 35.

A. forwardly extending index arm 36 is formed integrally with the bearing 32 and the forward end of said arm is provided with a slot 37 in which is revolubly mounted the forward end of the index lever 38, said end being provided with a hole through which freely passes the pin 39, said pin being riveted in holes provided in the ears 4040. The'rear end of the lever 38 is provided with a hole in which is revolubly mounted the pin 41. The pin 41 is riveted in holes spectively, in the large cylindrical hole 46 H and the small cylindrical hole 47 provided in the index guide 48. The index guide 48 is formed integrally with the flange 49 and the latter is secured to the side 17 by means of screws such as 50.

A retracting spring 51 is mounted in the large cylindrical hole 46 of the index guide 48 and presses toward the right against the large cylindrical portion 44 of the index sleeve 43. The index sleeve 43 is provided with a large cylindrical hole 52 and a small. cylindrical hole 53, the right end of the large hole being closed by the plug 54, and the latter is secured in place by the pin 55. The index pin is composed of a small cylindrical portion 56 and a head 57 which slide freely, respectively, in the small cylindrical hole 53 and the large cylindrical hole 52 of the index sleeve 43, and a relieving spring 58 is placed in the latter hole between the head 57 and the plug 54, the pressure of said spring acting to normally keep the a point 59 of the index pin in the position shown in Fig. 1. 1

The inner boss 60 of the index guide 48 is provided with a slot 61 in which slides freely the screw 62, the latter being threaded into a hole in the small cylindrical portion 45 of the index sleeve 43, the ends of said slot serving to limit the motion of the index sleeve 43 in both directions.

A plurality of index sockets such as 63 is provided, each socket being driven in a hole in the flange 24, there being one index socket for each of the shelves 25 and each socket is so located that when its corre spon'ding shelf 25 is in the position shown as occupied by the shelf A in Figs. 1 and 2, thehole 54 in said socket shall be opposite the point 59 of the index pin. The hole 64 is somewhat larger in diameter than'the small cylindrical portion 56 of the index pin and the head of said socket is provided with a chamfered portion 65 for a purpose hereinafter explained.

Since the index guide 48 is fixed in position, it is evident that the index sockets 63 are located at equal radial distances from the center of the shaft21.

A sleeve 65 is IGVOlllJiJlji' mounted upon the shaft '30 in front of the end of the hear ing 32 and a rearwardly extending arm 67, provided with the cam 68, is formed integrally therewith-the cam 68 being located and shaped to contact withthe cam follower 69, whichis form d integrally with the lever 38 for a purpose hereinafter explained.

The index wheel 70 is formed integrally with the sleeve 71 and the latter is provided with a hole which fits tightly upon the front end of the shaft 30 and said sleeve is secured to saidshaft by means of the pin 72. The face of the index wheel 70 is provided with a plurality of index holes 73,

there being one index hole for each of the shelves 25. Said face is further provided.

each of the shelves 25.

The literal indicia 74 corresponds to the literal indicia 75 placed at the ends of the horizontal lines upon the index 98 in Fig. 1. There is one horizontal line on said index for each of the shelves 25 and said horizontal lines are divided into a plurality of vertical series equal in number to the number of stamps that are to be placed upon each of the shelves 25, and each vertical series is designated by a numeral.

The stamp rack is provided with a cover 76, inking pad 77, cover for the inking pad 78,' a table 79 and a bracket 80 for supporting said table, all of these parts being similar to those shown, described and claimed in my application for U. S. Letters Patent, Serial No. 149126, filed Feb. 16, 1917.

A selecting arm 81 is formed integrally with the sleeve 66, said arm being U shaped in contour and extending around the rim of the index wheel 70. At the bend of the U the arm 81 is provided with an index pointer 82, formed integrally with said arm and the forward limb of the U is provided with a boss 83 and a selecting pointer 84 formed integrally therewith. The boss83 is threaded and a sleeve 80 is screwed thereupon, said sleeve being provided with an extension 86. The boss 83, sleeve 85 and extension 86 are provided, respectively, with holes 87 and 88 mutually in line and in said holes, there is slidably mounted the selecting pin 89, said pin being nrovided with an enlarge inent 90 between which and the inside of the top of the sleeve 85 there is placed a spring 91 which serves to normally keep the pin 89 in the position shown in Fig. 5. The pin 89 is provided with a handle 92. A detent' pin 93 driven tightly into a hole provided in the pin 89 and said pin slides freely in the slot 94 provided in the extension 86.

An index bracket 95 is secured to the front 18 by screws 96 and said bracket is provided with an index point 97 which is located adjacent to the rim of the wheel 70.

The operation of my improved stamp rack is as follows By an inspection of the index 98 the operator ascertains the horizontal line upon which the stamp that he desires to use is in- V 89 from the index hole 73 in which it may be resting and gives the handle 92 a slight motion of revolution, thus bringing the detent pin 93 over the outer face of the extension 86 and preventing the point of the selecting pin from reentering the index hole 7 8.

The operator then moves the selecting arm 81 in either a clock-wise counter clockwise direction until the selecting pointer 84 comes opposite the one of the literal indicia T l that corresponds to the literal indicia 7 5 that is at the end of the horizontal line of the index 98 upon which the desired stamp is indexed.

The operator then turns the handle 92 until the detent pin 93 drops into the slot 9 1 and permits the point of the selecting pin 89 to enter the one of the index holes 73 that corresponds to the literal indicia 74 that is opposite the selecting pointer 84.

It is evident that when the point of the selecting pin 89 enters the appropriate one of the indexing holes 78 the index wheel 70 and the selecting arm 81 will be locked together.

The operator .then turns the index wheel 70 in either a clock-wise or counter clockwise direction until the index pointer 82 comes opposite the index point 97.

When this happens, the shelf desired will occupy the position shown as occupied by shelf A in Figs. 1 and 2.

The operator then has merely to note the numerals placed upon the shelves just below the stamps and select the stamp corre sponding to the numeral that is the same as the numeral at the head of the vertical series in which the desired stamp is indexed upon the index 98.

It is to be noted that the cam 68 contacts with the cam follower 69 only when the pointer 82 is opposite the point 97 or near thereto; at other times, said cam and cam follower are out of contact as shown in Figs. 1 and 3, and the retracting spring 51 keeps the index sleeve i3 and lever 38 in the positions shown in Fig. 1 and shown by full lines in Fig. 3. When, however, the pointer 82 is approaching the point 97 the cam 68 contacts with the cam follower 69 and moves the lever 38 from the position shown by full lines in Fig. 3 to the position shown by dotted lines in said figure, thus moving the point 59 of the index pin to the position shown dotted in Fig. 1, and causing it to enter the hole 6% of the index socket 83 and lock the flange 24 in position.

It is to be noted that during the approach of the socket 63 to the position in which it is opposite the point 59 of the index pin, said point bears against the chamfered portion of said socket and causes said point to move toward the right against the resistance of the relieving spring 58 until said point is oppositethe hole 64:, and then said spring forces the point 59 within said hole.
